CHANNELlNG-IVIACHINE.

SPECIFICATION formingpart of Letters Patent No. 788,809, dated May 2,1905.

Application iiled May 5, 1902. Renewed lilly 30, 1904. Serial No.218,807.

To all, whom t may concern.

Be it known that I, ANDREW A. AIILQUIs'i, a citizen ofthe United States,residing at South Easton, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements inChannelingdvlachines; and I do hereby declare the following' to be afull, clear, and exact description of the invention,.such as will enableothers skilled in IO the art to which it appertains to make and use thesame.

The present invention relates to channeling-machines for channeling' thesoles of boots and shoes. Such machines comprise a chan- I5 neling-knifewhich makes an incision in the sole to form a channel and a channel iapor lip, which is subsequently turned up in order to open the channel forthe reception of the stitches or other fastening devices by which 2o thesole is secured to the other portions of the shoe. The operation ofturning up the lip is usually performed upon a separate machine,although machines have been devised which are designed to channel thesole and turn up the lip at one operation. As I am advised as to thestate of the art, channeling-machines which are adapted to turn up thechannel Hap or lip have been provided with a stationary lip-turningdevice or with a lip-turning de- 3o vice arranged to vibratetransversely to the line of feed.

The object of the present invention is to provide a lip-turning'deviceof improved construction, arrangement, and mode of operationparticularly adapted for use in a channeling-machine whereby the sole ofa shoe can be `channeled and the lip turned up at one operation in asatisfactory manner, but which is also adapted for use in amachine whichmerely 40 acts to turn up the lip.

With this object in view my invention contemplates providing alip-turning` device arranged to remain in contact with the lip of ashoe-sole and shaped to turn up the lip and means for vibrating thelip-turning device Alongitudinally of the lip or in the line of feed. Byso vibrating the lip-turning device it is caused to move intermittentlyover the lip while in contact therewith and acts to turn over the lipand set it in position in a certain and reliable manner. On account ofthe intermittent action ofthe lip-turningn device less power is requiredto run the machine in which it is used than when a stationarylip-turning device is used, and the lip-turning device can beincorporated in asole-channeling machine without appreciabl y increasingthe power required to run the machine.

My improved lip-turning device is preferably embodied in achanneling-machine provided with a channeling-knife which is alsoVibrated in the line of feed and when embodied in such a machine ispreferably attached to the movable part ofthe machine which carries thechanneling-lniife, so that the same mechanism is utilized to actuateboth the channeling-kmfe and the lip-turning device. i V

My invention is intended, primarily, as an improvement on a class ofchanneling-ma chines well known in the art, an example of which isdisclosed in the patent to W. C. Meyer and Z. T. French, No. 630,339,dated August 8, 1899, and in the drawings accompanying this applicationI have illustratedmy invention embodied in a machine similar to thatdisclosed in said patent. While, however, my invention is particularlyapplicable to such machine and when embodied therein possessesadvantages in construction and operation which will be obvious to thoseskilled in the art, it is to be understood that it is not limited tosuch machine, but may be embodied in many different constructionswithout departingl from the spirit thereof.

Referring to the drawings, Figure l is a 35 view in side elevation of arough-rounding and channeling machine similar to the machine disclosedin Patent No. 630,339, above referred to, with my invention appliedthereto. Fig.

2 is a detail sectional View taken on the line 90 2 2 of Fig. 3,illustrating a portion of the knifecarricr with a channeling-knife andlipturning device secured thereto. Fig. 3 is a plan view of the partsillustrated in Fig. 2. Fig. L is a view in front elevation of the parts95 illustrated in Fig. Q, the sole-support being omitted. Figs. 5, 6,and 7 are views in plan, front elevation, and side elevat1on of aportion of the carrier and of a channeling-knife and lip-turning devicesecured thereto, illustrating a modified form of my invention; and Fig.8 is a detail view, in side elevation, looking in` the oppositedirection from Fig. 1, illustrating the action of the channeling-knifeand lip-turning device in cutting the channel and turning up the lip.

In the drawings, 1 indicates the frame of the machine. 2 the cam-shaftjournaled therein, 3 the oscillating arm pivoted at the rear of themachine-frame and extending beneath the cam-shaft 2 to the front of themachine, 4 the vertically-movable block mounted in the forward end ofthe horizontally-movable slide 5, mounted on the oscillating arm 3, 6the plate secured to the block 4, 7 the stud projecting downwardly fromthe plate 6 and secured at its lower end in a lug projecting from theblock 4, and 8 the sole-support rotatably mounted upon the stud 7, saidparts and all other parts illustrated in the drawings and nothereinafter otherwise specifically described being the same as thecorresponding parts of the machine illustrated in the patent abovereferred to, to which reference is made for a description of theirconstruction, arrangement, and mode of operation.

Referring to Figs. 2, 8, and 4, the channeling-knife is indicated at 9,the shank of the knife being arranged horizontally7 and the edge of theknife extending diagonally from the shank portion beyond the face of thework-support 8. The channeling-knife is secured above the work-support 8to the plate 6 and stud 7 by means of a clamping-block 10, which isreceived in a slot cut in one side of the upper end of the stud 7 andwhich is actuated by means of a clamping-screw 11, passing through thestud 7 and screwing into the block. The clamping-block is provided withan upwardly-projecting portion which forms a shoulder, between which andthe edge of the plate 6 the shank of the knife is clamped, the plate 6being provided with a notch to receive the shank of the knife and theupwardly-projecting' portion of the clamping-block.

During the operation of the machine the arm 3 is oscillated, as isclearly described in the patent above referred to, and thechanneling-knife is vibrated in the line of feed. In the form of myinvention illustrated in Figs. 2, 3, and 4 the lip-turning device isindicated at 12, and in order to cause it to vibrate in the line of feedit is secured` by means of a screw 18, to the clamping-block 10, as isclearly indicated in Figs. 3 and 4. As shown in these figures, thelip-turning device consists of a block or plate which extends forward infront of the clainpingblock and. toward the channelingknife and isprovided at its forward upper edge with a projection or horn. 14, whichis received in a notch formed in the rear portion of the l knife, sothat the lip-turning device is located in close proximity to the knife.Below the horn 14 the forward end and the outer surface of thelip-turning device are shaped to eng'age the lip formed by thechanneling-knife and turn it over and press it against the sole, as isindicated in Fig. 8. It will be seen that the lipturning device islocated in close proximity to the channeling-knife and follows the knifeand that by being secured to the same carrier as the knife vibratestherewith and is thereby caused to move intermittently along the lipwhile remaining in engagement therewith. The lip-turning device thusacts to turn up the lip and set it in position in a reliable andsatisfactory manner as soon as it is formed by the channeling-knife. Inactual practice it has been found that the addition of the lipturningdevice does not appreciably increase the power required to run themachine, and the machine is as satisfactory in operation as when usedsimply to channel the sole.

The cutting edge of the channeling-knife (illustrated in Figs. 2, 3, and4) extends obliquely to the surface of the sole.

In Figs. 5, 6, and 7 I have illustrated a modified form of lip-turningdevice in connection with a channeling-knife the cutting edge of whichis arranged more nearly parallel with the surface of the sole. Referringtothese figures, 15 indicates the channeling-knife, and 16 thelip-turning device. The Shanks of the channeling-knife and of thelip-turning device are both clamped between the upwardlyextendingportion of the clamping-block 10 and the edge of plate 6 and areintel-locked by means of a projection on one side of the shank of thechanneling-knife and a corresponding slot in the adjacent side of theshank of the lip-turning device. The forward end of the lip-turningdevice extends downwardly from its shank in close proximity to the rearedge of the blade of the channeling-knife and is provided with a curvedsurface, practically forming a continuation of the inner surface of theblade of the channeling-knife, which acts to turn over the lip and pressit against the sole. The shape of this surface and the manner in whichthelip is turned over and pressed against the sole will be obvious froman inspection of Figs. 6 and 7 without further description.

Having thus indicated the nature and scope of my invention and havingspecifically described a machine embodying a preferred form thereof, Iclaim as new and desire to secure by Letters Patent of the UnitedStates- 1. A channeling-machine, having, in combination, achanneling-knife, a lip-turning device vibrating in the line of feed,and means for actuating the lip-turning device, substantially asdescribed.
